I completely abandoned it as well. Ended up using either sprites.dev or cursor agents with my cursor subscription

How is sprites different from just setting up a VPS? How's the latency?

It is like a vps but it's on- demand (no ssh setup necessary since all that is abstracted away in d cli tool). You have the ability to spin up and shutdown/pause the sandbox. Its just another option among the ever growing list of running agents in a sandbox.
